“…Nanoparticles (NPs) may increase the plant's stress tolerance to increase phytoremediation as well as help in the alleviation of toxicity [118,119]. Nano-phytoremediation can effectively remediate the polluted soils/water using those plants that possess high efficiency for NPs/metal uptake [26,120,121], and can be used as an alternative solution for As phytoremediation (Figure 2). Application of nanoparticles for the management of contaminated agricultural lands and improvement of plant growth and developments has shown significant prospects [26].…”

Application of nanoparticles for the management of contaminated agricultural lands and improvement of plant growth and developments has shown significant prospects [26]. In this context, it was shown that nanostructured silicon dioxide can act as a potential agent that can improve the phytoremediation process to attain the desired outcomes [24,122].…”

“…Currently, the application of nanoparticles has become an acceptable approach for the reclamation of polluted ecosystems [20][21][22]. The concept of nano-phytoremediation technology has been emerging for the removal of contaminants from soil/water, which involves the application of both nanotechnology and phytoremediation [23][24][25][26]. However, the main challenge in using nanoparticles for the remediation of pollutants is the lack of an adequate number of reports proving its efficacy.…”

Arsenic contamination of the environment is a serious problem threatening the health of millions of people exposed to arsenic (As) via drinking water and crops grown in contaminated areas. The remediation of As-contaminated soil and water bodies needs to be sustainable, low-cost and feasible to apply in the most affected low-to-middle income countries, like India and Bangladesh. Phytoremediation is an aesthetically appreciable and successful approach that can be used for As decontamination with use of the best approach(es) and the most promising plant(s). However, phytoremediation lacks the required speed and sometimes the stress caused by As could diminish plants’ potential for remediation. To tackle these demerits, we need augment plants’ potential with appropriate technological methods including microbial and nanoparticles applications and genetic modification of plants to alleviate the As stress and enhance As accumulation in phytoremediator plants. The present review discusses the As phytoremediation prospects of soil and water bodies and the usefulness of various plant systems in terms of high biomass, high As accumulation, bioenergy potential, and economic utility. The potential and prospects of assisted phytoremediation approaches are also presented.

“…Also they affect the stomata function, photosynthetic activity and damage the root system [7][8] . In developing countries, the crops which are grown in the surroundings of heavy metal industries are affected with toxicity [9][10] . Cadmium is one of the more toxic and highly mobile element from soil to plants and then to food chain.…”

Vigna mungo generally called as black gram is a nutrient food crop which is widely used in Indian cuisine and also used in traditional ayurvedic medicine. By natural and anthropogenic activities, black gram growth is highly affecting by heavy metal pollution. Hence, it is necessary to conduct the experiments to know the effects of various heavy metals on growth of black gram in turn yield levels. In the current study, we aimed to study the in vitro effects of heavy metals such as chromium (Cr), cadmium (Cd), cobalt (Co) and lead (Pb) on germination of seeds and seedling morphology of black gram. The concentrations include 1, 10, 20, 50 and 100 ppm of respective heavy metal (Cr, Cd, Co and Pb) along with the two positive controls i.e. tap water (T.W) and distilled water (D.W) were used without any heavy metal for the preparation of media. Upon treatment, percentage of germination and both root and shoot lengths of black gram were significantly affected by increasing concentrations of cadmium, cobalt and lead when compared to controls. Specifically, germination percentage was reduced from 1 ppm to 100 ppm i.e. 77% to 46% with Cd, 64% to 50 % with Co and 78% to 70 % with Pb treatments. This data indicates that each heavy metal has its own impact on black gram seed germination. Similarly, shoot and root lengths were also reduced upon these heavy metal treatments. Although the percentage of germination decreased drastically (36% at 100 ppm) along with the increasing concentration of chromium, the root and shoot lengths were suddenly increased (hugely root length) when compared to controls. In conclusion, each heavy metal has its own critical point for each seedling or plant growth.

“…The nanoformulation has the benefits of easy cutaneous application and improved properties to combat inflammation, microbial infections, and carcinogenic effects. The review by Zhou et al provides an overview and a synthesis of the published literature regarding the NP applications for plant stress alleviation and growth stimulation [11]. By discussing the mechanisms of interaction between NPs and heavy metals, the review provides valuable information for NP applications in phyto-and soil remediation as well as sustainable agriculture.…”
